This unit currently has the absolute best value for money. The fact that it decrypted eg Dolby HD formats can Answering via HDMI as PCM through the PS3, Blu-ray enthusiasts come at their expense. The Onkyo 606, 506, 576 (previous 505 605) are far superior to their competitors, according to all test reports. The 605 (606) should sound slightly better than the 576 (which extends from 506 only by DD + and HDMI receiving different), but this is audible only at very high volumes. I think that the vast majority of these never take advantage (can) or the difference (probably) will not perceive. The higher power classes Onkyo 705, 805, etc .. or other brands are even more for geeks who need eg upscaler, which raises the question of whether these are better than in the conventional devices because good upscaler costs also not little. In connection with my 55Zoll FullHD TV and TwinHD satellite receivers, this receiver is certainly more than enough to enable home theater and hi-fi enjoyment. I think the difference between normal PAL television and HD is much larger than for example the difference between a Onkyo 506, 576 and eg 705th 10, 15 years ago, the cost of a receiver with the performance of this device, the three-fold. The service is very good, in my opinion, missing is just a simple level adjustment of individual boxes (eg Center), as this is possible only through the manual calibration. With my old cheap sorround-set this was possible with the simple push of a button. Next, the receiver is very warm. The manual describes that the distance to the top and to the side should be 20cm in a furniture. What, please, can you accommodate this equipment in a hi-fi tower, he can hardly stand as the top device in the chain so by its size and weight? It's certainly not advisable to make it hi-fi equipment, because at least long-term damage can occur (due to defective electrolytic capacitors). But this is a curse of all new receivers and is the Onkyo can not be blamed; the higher priced receivers should have even more heat. I do not know how hot the will. My old hi-fi amplifier are never more than lukewarm. Nevertheless clear recommendation
